Maybe related with bug1571513? Because we would still hold a lots of resource even if the pages got refresh.

[Alex Chronopoulos [:achronop]]

I expect that Bug 1571513 will improve the situation here since some of the memory will be cleaned but not everything. Refreshing the page is not enough to clean up the page from the memory. Clean up is taking place when tab is closing. So the same error can be reproduced with any page.

I believe it is some kind of caching that keeps the page in the memory. I don't know the details. I re-assign the bug in a general DOM component in case they know better what should happen on page refresh. Feel free to change it, if it is not the right component for that.

Hi Andrew, could you please take a look and suggest the priority for this one?

This sounds like a dupe of bug 1610193.
